NON-PROJECTING HINGE.

T 0 all whom it may concern:

Be it known that I, JosErH R. ANGELO- vIoH, a citizen of the UnitedStates, residing at San Francisco, in the county of San Francisco andState of California, have invented new and useful Improvements inNon-Projecting Hinges, of which the following is a specification.

The object of the present invention is to provide an improved hinge forhinging sewing machines, or other, tables, doors, box covers or otherobjects when it is desirable that the hinge should not project above thesurfaces of the parts hinged together.

I have herein shown the invention as applied to the table of a sewingmachine, but it will be readily understood that it may be equally wellapplied to other tables, doors, or other objects.

In the accompanying drawing, Figure 1 is a broken front view of a sewingmachine table equipped with my improved hinge; Fig. 2 is an enlargedbroken plan view of the same, extended; Fig. 3 is a sectional view ofthe same, extended; Fig. 4 is a similar view of the same closed; Fig. 5is a sectional view on a still larger scale of the hinge in the extendedposition of the table; Fig. 6 is a detail sectional view.

Referring to the drawing, 1 indicates a table, and 2 an extension hingedthereto by my improved hinges. In recesses 3 in the vertical edge of thetable are secured by screws 4 straps 5 of hinges, and the otherstraps 6thereof are secured, by screws 7 to the bottoms of recesses 8, formed inthe upper surface of the extension 2 of the table. Each strap, exceptthe bearing thereof, is concealed by a plat-e or block 9 of wood fittingsnugly within the corresponding recess. To said vertical edge is secureda molding 12, and the adjacent edge of the extension 2 is so formed thatsaid molding supports said extension in a horizontal position whenextended. Said straps 5, 6, of each hinge are bent around at their endsto form hearings or eves 13, in which are received the sides of a loop14 by which the extension is hinged to the table. In order to insurethat the loop shall be horizontal when the extension is extended, thebearing or eye of the strap secured to said extension is formed with acurved projection 15, which, in the extended position of the extension,fits snugly beneath the eye of the other Specification of LettersPatent.

strap. In the swinging of the extension upon its hinges, the projection15 engages the rounded lower portion of the bearing of the other strapand causes the two hearings to assume the same horizontal level.

The outer surface of the movable bearing or eye 13 is not accuratelycylindrical, for, if it were so made,'the result would be that, in manycases, in swinging the extension 2 on its pivot, the loop 14 would notlie inthe same plane as said extension. That is to say, said loop 1 1would permit the extension to shift without turning, so that theextension 2 might not lie on the table 1 with its ends properlyregistering with the ends of said table, but might be shiftedlongitudinally relatively thereto. this result, 1 enlarge the outersurface of the bearing 18 or shape it in the form of a cam as shown at16, so that the bearing 13 of the extension 2 cannot turn on the loop 14without said cam-shaped portion binding against the outer surface of theother bearing 13. In consequence of said binding, the movable bearing 13rolls upon the fixed bearing 13 when the extension is moved from itsoutermost position. But, when said extension has been turned throughmore than a right angle then said camshaped portion 16 enters a cavity17 formed in the outer surface of the fixed bearing 13, so that theextension 2 is properly centered upon the table 1.

It will readily be seen that with a hinge of this construction, theextension top, when in its extended position, will lie perfectly levelwith the table top proper, and the hinge will not project above saidlevel. The construction therefore is very advantageous for sewingmachines or other tables, in which it is desirable that light fabricsmay be moved on said table withoutmeeting with any obstruction. Thehinge is also useful, whenever it is required that it should not projectabove the surfaces of the objects connected by said hinge. It will. alsoreadily be seen that this improved hinge permits the extension to lieclose against the upper surface of the table when in a closed position.

I claim 1. A non-projecting hinge for hinging together two objects suchas a table and an extension thereof, comprising a strap in a recess inan edge of the table and secured to In order to avoid said table andhaving an eye extending up to, but not above the surface of the table,and a strap secured to said extension having an eye extending to, butnot above, the surface of the extension, and a loop having sides eachengaging one of said eyes, one of said straps having a projection orfinger arranged to engage the eye of the other strap to insure theparallelism of the loop With said surfaces When in the extendedposition.

2. A non-projecting hinge for hinging together two objects such as atable and an extension thereof, comprising a strap in a recess in anedge of the table and secured to said table and having an eye extendingup to'but not above the surface of the table, and a strap secured tosaid extension having an eye extending to, but not above, the surface ofthe extension, and a loop having sides each engaging one of said eyes,the extension strap-eye having an enlarged cam-shaped portion adapted tobind upon the other strap-eye When the extension is moved from itsextended position, and said other strap-eye having a cavity adapted toreceive said cam-shaped portion When the extension is moved intoitscollapsed position.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing Witnesses.
